Purpose: Knowing the features of dental evolution and facial morphology, marked by an increase in the prevalence of agenesis and a tendency towards verticalization of the face, the main objective of this cross-sectional observational study was to assess the correlation between the occurrence of agenesis (of 3rd molars or other teeth) and facial morphology in the French population.
Methods: The study was conducted at the University Hospital of Rennes, France, from June 2022 to October 2022. Patients aged 12-18 years who underwent a global orthodontic assessment were included.

Aim: Evaluate constitutional differences in chin morphology and volume, and mandibular tooth size, between different facial divergence patterns.
Materials And Methods: The sample consisted of 284 pretreatment cone beam computed tomography (CBCT) images of growing and non-growing patients who were stratified into 4 groups based on mandibular plane inclination to cranial base (SN) angle. Linear and angular measurements were made on the lateral CBCT images: mandibular lateral incisor crown (I-C) total (I-A) lengths, the distances between point D (centre of symphysis) and both incisor apex (D-A) and menton (D-Me) and between cemento-enamel junction and menton (CEJ-Me); chin width at the level of the central incisor apex (CWA) and point D (CWD); and the angles of the anterior and posterior symphyseal slopes.

A 61-year-old edentulous patient presented with dental problems. Examination revealed a very narrow alveolar process in the symphysis area of the chin, with moderate vertical resorption. The decision was made for bone augmentation by means of harvesting an autologous bone graft from the alveolar process.

Introduction: This study aimed to assess the bony and soft tissue parameters at mandibular symphysis among skeletal Class III patients with different vertical growth patterns, using cone-beam computed tomography (CBCT).
Materials And Methods: CBCT images of 60 skeletal Class III non-growing patients were evaluated (mean age 24.9 ± 8.

Background/aim: Mandibular condylar fractures in pediatric patients may exhibit distinct epidemiological characteristics attributed to their unique growth and development phase, as well as various anatomical, physiological, biomechanical, and behavioral factors that differentiate them from adults. This study aimed to investigate the demographics, injurious factors, classifications, clinical manifestations, and treatments of pediatric mandibular condylar fractures, as well as the concomitant injuries in maxillofacial and other body parts.
Materials And Methods: This retrospective study analyzed the clinical data of 189 pediatric patients with mandibular condylar fractures between 2011 and 2022.
